Add support for armhf/gnueabihf resulting in new 'os.and.arch' := [ 'android-armv7hf' and 'linux-armv7hf' ]

- Platform gets new ABIType [ GENERIC, ARMEL, ARMHF ]

- Platform impl. needs to guess ABIType in case of ARM,
  since no Java system property ('os.arch' ..) reflects the new EABI.
  I consider this a bug, since this will also hinder JNLP to work.
  The latter also uses 'os.arch' sys property to determine the nativelib resource!
  (See Platform.guessABITypeImpl(..) for details how we guess the type.)

- Adding symbolic links to ubuntu's gnueabihf cross tool chain

- Adding armhf crossbuild script
